In the following detailed description, and the drawing, like reference characters indicate like parts. I

As shown in Figs. 1 and 2, the cable connector of this invention includes a main member which includes two flat spaced oppositely extending parallel terminal plate portions i2 and a cross bar portion 13 disposed at substantially right angles to the plate portions and connecting adjacent ends thereof. Each face of each flat portion [2 is provided with intersecting medial longitudinal and transverse grooves indicated at I4 and I6, respectively, in

Fig. 2.

The grooved faces of flat portions I2 co-opcrate with connector plates IT to grip cables it. Each face of each connector plate is provided with intersecting medial longitudinal and transverse grooves indicated at H) and 2 I, respective- 1y, which are complementary to the grooves of the flat portions of the main member. The plates are mounted on the flat portions of the main member with the grooves in registry. Bolts 22, which pass through bores 23 in the corners of the plates l1 and through bores 24 in flat portions l2 draw the plates toward the flat portions no s he. ain membe is c amp. the tab e the be we n n he ew; Qt he cab e onne to shown in e- L t e s ene slat s a e mo nte n ns rors pss d aces at the fla er-dons s i ember it, the ab es may be of such i meter t t the axes 0 h sabls a bs a tia y n; 2 at hat t se lea an h ca es will a the xe hs il n Fiee seam dense assemb s sheen in b eiis t cables i and 2 which me to form s s o n the ca es re Q such d m r t at th axes sissth ables fe in u n ia a single pla e In i 3 and s essnes tss Pis l s ed it main memb r 21 wh ch i n r l m a n c nstruction t mem er- Is o for a e m nal. 1e- E sh fla n rtiqn of main e e 2 1s rov de with a cen ral bQrs s A, t sX snd-s t q ieh t bore n one of th plate port ons hol s one ss Q th t plate portion ag i st sus ba 32 ort l k h other p at ss on and th c nn ct r la s en age d g ip ne e d o v a b e 32-.

T e c nn t plate and m n. m mbe may be assembled in various other ways. For example, an additional connector plate can be mounted on the outer side of one or both of the fiat portions of the main member if it is desired to connect additional cables to the clamp. In addition, one or more connector plates may be mounted on the outer side of each of the connector plates or several connector plates can be mounted one on top of another.

Various other modifications of the invention will be apparent to those skilled in the art, and the cable connector described above and illustrated in the drawing is subject to structural modification without departing from either the spirit or the scope of the invention as set forth in the appended claims.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A cable connector which comprises a main member having a pair of oppositely extending spaced fiat parallel terminal plate portions and an integral connecting portion disposed at substantially right angles thereto and joining adjacent ends thereof, a pair of fiat connector plates, each of said connector plates being on the inner side of one of said terminal portions, the inner side of each of said terminal portions having a groove extending linearly of the main member, at least one of said connector plates having a groove extending transversely of the main member, each of said connector plates having a grooveopposite and complementary to each groove in the adjacent face of the terminal portion associated therewith, the ends of said grooves being unobstructed, and means for drawing each of said connector platestoward the terminal portion associated therewith, whereby the connector is adapted to grip a cable in the grooves at each end thereof, the connecting portion of the main member being of such length that the axes of the cables are in substantially the same plane.

2. A cable connector which comprises a main member having two flat oppositely extending spaced parallel terminal portions and an integral connecting portion disposed at substantially right angles thereto and joining adjacent ends thereof, a pair of flat connector plates each of substantially the same size and shape as one of the terminal portions of the main member, said connector plates being disposed on opposite faces of the terminal portions, there being complementary intersecting longitudinal and transverse grooves in the opposite faces of the terminal portions of the main member and in the adjacent faces of the connector plates, the ends of said grooves being unobstructed, and means for drawing each of the connector plates toward the terminal portion of the main member associated therewith, said complementary grooves being adapted to receive cables, whereby the cables can be clamped in said connector in parallel, crossing or substantially aligned relation.

3. A cable connector which comprises a main member having two flat oppositely extending spaced parallel terminal portions and an integral connecting portion disposed at substantially right angles thereto and joining adjacent ends thereof, a pair of fiat connector plates each of substantially the same size and shape as one of the terminal portions of the main member, said connector plates being disposed on opposite faces of the terminal portions, said opposite faces of the terminal portions each having a groove extending linearly of the main member, each of said connector plates having a groove opposite and complementary to the groove in the adjacent face of the terminal portion associated therewith, the ends of said grooves remote from the connecting portion being unobstructed, and means for drawing each of said connector plates toward the terminal portion of the main member associated therewith, said complementary grooves being adapted to receive cables, whereby the connector is adapted to grip a cable in the grooves at each end thereof, the connecting portion of the main member being of such length that the axes of the cables are substantially in alignment.

4. A cable binding and splicing clamp comprising an elongate unitary member having a pair of flat parallel end portions of substantially equal size and shape joined by an intermediate portion perpendicular thereto, the end portions having opposed major faces, each of said opposed major faces being provided with intersecting medial longitudinal and transverse grooves of substantially semi-circular transverse section, a plurality of members of substantially the size and shape of one of the end portions of said unitary member, and a plurality of actuating means whereby at least one of the plurality of members is retained in coinciding opposition to each endportion of said elongate member for clamping cables in substantially co-planar relation between said members.
